I see a few problems that can be corrected:

• no documentation. How do i use this? Where do i start? You provide no clues for the end user.
• no standardization. Try using Module::Starter to create the framework for your distribution.
• custom installation with no uninstall. You could utilize Makefile.pl instead:

  EXE_FILES => ['colorapt/capt-get','colorapt/capt-search','colorapt/cap
  +t-cache']
  [download]

  This delegates installation to something like cpanm, which also provides the means to uninstall. (See ExtUtils::MakeMaker for more.)
• finally, is this really the best way to accomplish the task? I would think one module and one Perl script (no shell scripts) would suffice. Have the end user pipe the output of apt-get into your script instead of doing that for them.
